GAS-SBURN ER ATTACHMENT.

Specification ofLetters Patent.

Patented oct. 9, 1 90e.

Application filed January 30ll 1.906. Serial No. 298,684.

Be it known that I, ARTHUR D. ZIMMER- MAN, a citizen of theUnited States, residing at Boody, in the county of Macon and State of Illinois, have invented new and useful Improvements in Gas-Burner Attachments, of which the. following is a specification.

This invention relates to gas-burner attachments, and has for its object toprovide a combined valve and socket-head for drop-lights and theV like, whereby it is impossible to remove the socket-head from the gas-iixture without rst shutting oif the flow of gas, the operation of the shutting off of gas being automatic and accomplished at the same time that the socket is removed.

A further object of the invention is to provide a device of the character above referred l.to which may be economically manufactured taching the same therefrom.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination, and arrangement of parts hereinafter fully described, illustrated, and claimed.

In thel accompanying drawings, Figure 1 is an elevationof a gas-'xture, showing the relation of the attachment thereto. Fig. 2 is an enlarged side elevation of the combined socket-head and valve complete. Fig. 3 is a vertical diametrical section through the socket head, showing the valve in elevation therein. Fig. 4 is a section similar to Fig. 3, but taken at right angles thereto and showing the position of the parts when the gas is turned on. Fig. 5 is avertical diametrical section through the valve, showing the valve closed. Fig. 6 is a horizontal section through the valve on the line 6 6 of Fig. 3. Fi 7 1s a view similar to Fig. 5, showing the va ve open. Fig. 8 is a cross-section through the valve on the line 8 8 of Fig. 4. Fig. 9 1s a top plan view ofthe valve-casing with the valve and other parts omitted.

Referring to the drawings, 1 designates a valve-casing which is internally threaded at its base, as shown at 2, adapting the same to be screwed upon the threaded nipple of an ordinary gas-fixture, as shown in Fig. 1, in place of the ordinary gas-tip holder. The casing 1 is provided with a taper bore 3, in which is fitted a taper valve 4, said valve being chambered out, as shown at 5, and proi. vided with lateral ports or holes 6, extending outward from the chamber 5 and adapted to be thrown into vand out of communication with gas-ports 7 in the form of slots extending from the upper edge of the valve-casing 1 downward, as shown in Figs. 3 and 4, far enough to reach to the ports or holes 6 when the latter are turned to register therewith, as shown in Figs. 4 and 7. Fitted to the upper end of the valve 4 is a washer or cap 8, having the usual shouldered connection with the valve and connected thereto by means of a retaining-screw 9. The washer or cap 8 is provided at diametrically opposite points with notches 10, adapted to be moved into and out of register with the slots 7 in the valve-casing 1, the notches and slots being shown as registering in Fig. 4, while in Fig. 3 they are shown out of register. When in register, the gas from within the casingA 1 may pass into the chamber 4, outward through the openings or ports 6 into the slots 7, and upward through the notches 10 into theupper portion of the socket-head and thence to the burner, as will hereinafter appear.

Extending upward from the washer or cap 8 are twin lugs 11,spaced apart, as shown in Fig. 5 ,so as to straddle a lug or cross-bar 12, carried by a socket-head 13, as best shown in Fig. 3. This socket-head is made tapering to lit over the valve-casing 1 in the manner shown in Figs. 3 and 4 and rests upon a knurled or ornamental flange 14 at thebottom of the valve-casing, and said head is provided with a bayonet-slot 15, which engages a pin 16, projecting outward from the valvecasing 1. The horizontal portion of the bayonet-slot 1 5 is of sufficient length to enable said socket-head to be given a quarter-turn before the pin- 16 reaches the end of such horizontal portion of the slot, and the entrance portion or throat of the slot is so arranged that when it is passed over and into engagement with the pin 16 the cross-bar or lug 12, carried by the socket-head, will just be in a position to enter between the twin lugs 11 of the cap or washer 8. In turning the socket-head 13 until the pin 16 has traversed the horizontal portion of the bayonet-slot 15 the cross-bar 12, coacting with the lugs 11, imparts a quarter-revolution to the valve 4, thus bringing the outlet-ports 6 thereof into register with.

the slots 7 of the valve-casing, thereby turning on the gas. In order to remove the socket-head from the gas-fixture, the operation above described has to be reversed, the

IOO

pin 16 traveling to the opposite end of the slot, which has the effect of turning the valve 4 back to the position shown in Fig. 3, carrying the orts 6 out of register with the slots 7 and a so carrying the notches 10 out of register with said slots 7, thereby shutting H the gas. The socket-head 13 is shown as equipped with the usual gooseneck or tubular extension 17, to which may be connected the usual fieXible gas pipe or tube 18, leading to the drop-light or burner or other source to be supplied.

From the foregoing description it will be seen that it is impossible to remove the socket-head from the as-fixture without automatically turning o the gas, and, conversely, in applying the socket-head to the gas-fixture the gas is necessarily turned on. It is important to disconnect the gas tube or pipe of a drop-light whenever the same is not in use, as the tube rapidly rots when allowed to remain filled with gas or when it is left connected to the gas-burner. The danger of such removal is obviated by means of the devices hereinabove fully described, it being impossible to detach the socket-head without shutting off the as. The connection between the socketead and the gas-fixture may be quickly and easily effected, and the same is true with regard to disconnecting the socket-head therefrom. 4

It will of course be understood that the invention is susceptible of changes in the form, proportion, and minor details of construction, which may accordingly be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

I claim- 1. A gas-fixture provided with a valve and valve-casing, in combination with a sockethead for dro -lights and the like removable from the valve, said socket-head carrying means for engaging and operating said valve,

Vand also retaining means whereby the sockethead is locked to the valve-casing.

2. A valve and valve-casing applicable to an ordinary gas-fixture in lace of the usual burner, in combination with a socket-head for drop-lights and the like adapted to fit detachably over said valve and interlock with the valve-casing by a rotary movement, said socket-head carrying means foropening and closing the valve in the locking and unlocking operation. y

3. A valve adapted to be applied to a gasiixture in place of the ordinary burner and embodying one or more lugs connected with the valve roper, in combination with a socket-hea for drop-lights and the like adapted to fit over the valve-casing and carrying means for engaging said lug or lugs and also means adapted to interlock with the valve-casing, the valveoperating and the interlocking means being so related that the valve is opened andclosed by a partial rotary movement of the socket-head, simultaneously with the locking and unlocking of said head relatively to the valve-casing.

4. A gas-valve adapted to'be applied to a gas-fixture in place of the ordinary burner and comprising a valve-casing provided with a projecting pin, and a valve proper rotatable on a vertical axis and provided with one or more projecting lugs, in combination with a socket head for drop-lights and the like adaptedto fit over the valve-casing and provided with a bayonet-slot to engage the projecting pin thereof, and further provided with a crossbar adapted to en age the lug or lugs of the valve proper, said bayonet-slot and pin being so arranged that in the locking and unlocking of the socket-head, the cross-bar thereof cooperates with the lug or lugs of the valve to open or close' the latter, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
